Re: Modern
russian derivatives

: There are English words which are "borrowed"
from the Russian, such as "dacha", "samovar", "troika".

: Having "borrowed"
them for such a long time it is unlikely we shall give them back.

: Then there
are more recent terms, such as "glasnost" and "perestroika", but they appear to
apply to a specific period rather than being in general use.

: psi

There's
gulag, too, but not a whole lot more. The Russian language is on a decline mirroring
the deathspiral of the Soviet empire. In the '60s when I was in college, those
of us who studied Russian called ourselves the optimists. (The pessimists would
study Chinese....)
